Pain is a universal human experience, but we understand very little about the mechanics behind it. We hurt ourselves, we feel pain, we seek help from a professional or learn to avoid certain behaviours that cause pain. But the story of what goes on in our body is far from simple. Even medical practitioners themselves often fail to grasp the complexities between our minds and bodies and how they interact when dealing with pain stimulus. Common conception still equates pain with tissue damage but that is only a very small part of the story - the organ which produces pain is the brain. Pain is a complex mix of nerve endings, psychological state, social preconceptions and situational awareness. Using case studies and medical history, Dr Lalkhen guides us through all aspects of pain, from chronic to acute, and the current landscape of pain treatments - from medication to electrical nerve stimulation.
